As shown in Figures 2 and 3, the first clustered instrument board 16 is positioned at the front of the second clustered instrument board 18 along the direction of arrow X1 indication, have the highest speed of a motor vehicle of checking frequency for showing.Therefore, if the first clustered instrument board 16 and the distance of the eyes 47 of chaufeur 48 are 1m or farther, so the chaufeur 48 of steering vehicle 11 just can watch the first clustered instrument board 16 attentively than being easier to.Like this, chaufeur 48 reliably has the information that height checks frequency, as the speed of a motor vehicle depending on recognizing.

Referring to Fig. 1 to Fig. 3 and Fig. 6 A to Fig. 8, illustrated by comparative example, the vehicular instrument device 10 of the present embodiment can allow the movement of the sight line 49 of chaufeur 48 be less than the movement of the sight line 49 of chaufeur 48 in vehicular meter apparatus 51.The vehicular instrument device 51 of comparative example is conventional vehicular instrument device, and as shown in Figure 6 A and 6B, this device has instrument 54 and 57.

Fig. 6 A is the lateral plan of sight line 49 move mode when chaufeur 48 sees vehicular instrument device 51.Fig. 6 B is front view, represents the mode of sight line 49 movement when chaufeur 48 watches the instruments 54 and 57 and the mode of the visual field 56,58 change when sight line 49 moves.

With regard to the vehicular instrument device 51 of comparative example, as shown in Figure 6 A and 6B, when sight line 49 is from the outlook 37 of chaufeur 48 towards vehicle 11 front (by arrow X1 indication), instrument 54 is that the region inside the bearing circle 12 in the visual field 58 is in sight, and instrument 57 is then that the central area of instrument carrier panel 14 outside bearing circle 12 is in sight.Instrument 54 has central axis 55, and this central axis 55 is from the central area of the central axis 59 deflecter dash board 14 of bearing circle 12.

Be sitting in chaufeur 48 on seat 46 in order to the information be presented in instrument 54,57 can be seen, as the speed of a motor vehicle, chaufeur 48 must vertically and on even keel move its head, so that sight line 49 is turned to instrument 54 and 57 from the perimeter of vehicle front (being represented by arrow X1).

Specifically, as shown in Figure 6A, in order to check the information be presented in instrument 54, as the speed of a motor vehicle, chaufeur 48 will through front windshield 44 and towards the outside the sight line 49 in region be moved down in instrument 54, now, as shown in Figure 6B, the visual field of chaufeur 48 is reduced to the scope of 56 expressions from the scope that 58 represent.Result is exactly, and checks through front windshield 44, the chaufeur 48 of instrument 54 can see that the visual field of perimeter is reduced to the visual field 61 near boundary line 45, and this visual field 61 is by representing the long and short dash line of field range 56 and representing that the solid line of front windshield 44 framework is formed.

So, when chaufeur 48 watch the instruments 54 time, enough large field range just can not be had to go to see perimeter, therefore, the people that finds in the short period of time to appear at car two 11 front (shown in arrow X1) and thing may be difficult to.In this situation, chaufeur 48 needs its sight line to move down a longer distance moved on to from the center of front windshield 44 instrument 54.Central axis 55 due to instrument 54 is offset from the central axis 59 of bearing circle 12, so the chaufeur 48 be sitting on seat 46 is also just forced to keep a kind of factitious vehicle driving posture to carry out steering vehicle 11.

In order to check the information be presented in instrument 57, its sight line 49 is shifted to the instrument 57 (see Fig. 6 B) being positioned at instrument 54 left side by chaufeur 48 from the display centre 63 of instrument 54, now, the distance of sight line 49 movement is in the horizontal direction greater than the distance of movement in vertical direction, therefore, the time of sight line 49 parallel motion is longer than the time of vertical movement.

Therefore, chaufeur 48 can not have the suitable visual field, perimeter, and its sight line 49 must be moved a longer distance.Furtherly, because instrument 57 is located at the central area of instrument carrier panel 14, so the chaufeur 48 be sitting on seat 46 is just forced to keep factitious vehicle driving posture to carry out steering vehicle 11.

When its sight line 49 is shifted to front windshield (see Fig. 6 A and Fig. 6 B) from the display centre 64 of instrument 57 by chaufeur 48 obliquely, chaufeur 48 can obtain a suitable outside visual field, but needs sight line 49 to move a longer distance.

As shown in Fig. 1 to 3 and Fig. 7, with regard to the vehicular instrument device 10 of embodiment of the present invention, the center (seat center) of the display centre 21 of display centre 19, second clustered instrument board 18 of the first clustered instrument board 16, the center of bearing circle 12, the center of steering shaft 53 and seat 46 is all positioned on axis 39 along central axis 52 is coaxial.Therefore, when its sight line 49 is shifted to the first clustered instrument board 16 from vehicle 11 front (representing with arrow X1) by chaufeur 48, sight line 49 is vertically movement only.So the distance of sight line 49 movement in the vehicular instrument device 10 of present embodiment will much smaller than the distance of sight line 49 movement in the vehicular instrument device 51 (see Fig. 6 A and 6B) of comparative example.

In addition, the first clustered instrument board 16 display has the highest speed of checking the vehicle 11 of rate, and is positioned near boundary line 45, and from outlook 37, the position residing for the first clustered instrument board 16 is darker than the position residing for the second clustered instrument board 18.So compared with the vehicular instrument device 51 in comparative example, the vehicular instrument device 10 in present embodiment makes chaufeur 4 more easily watch the display surface (panel 17) of the first clustered instrument board 16 attentively.Therefore, chaufeur 48 can suitably depending on recognizing as display information such as the speed of a motor vehicle.

In sum, because the center (seat center) of the display centre 21 of display centre 19, second clustered instrument board 18 of the first clustered instrument board 16, the display centre of bearing circle 12, the center of steering shaft 53 (see Fig. 3) and seat 46 is all positioned on axis 39 along central axis 52 is coaxial, so chaufeur 48 naturally can carry out steering vehicle 11 by vehicle driving posture, the first clustered instrument board 16 and the second clustered instrument board 18 can be checked simultaneously.

When its sight line 49 is shifted to the display centre 19 of the first clustered instrument board 16 by chaufeur 48 (see Fig. 2 and Fig. 3), then can form the visual field 66 being positioned at the visual field 56, in this visual field 66, chaufeur 48 can see perimeter through front windshield 44, namely, as shown in Figure 7, the visual field 66 is by representing the long and short dash line of field range 56 and representing the scope that the solid line of boundary line 45 is formed.And in comparative example, its sight line 49 is shifted to instrument 54 by chaufeur 48, perimeter in the visual field 61, that is, as shown in Figure 6B, the visual field 61 is that in contrast to this, the visual field 66 is wider by representing the long and short dash line in the visual field 56 and representing the scope that the solid line of boundary line 45 is formed.

So; as shown in Figure 8; vehicular instrument device 10 in present embodiment makes chaufeur 48 suitably can check the activity of perimeter in the visual field 60 (the moment visual field); the information on the first clustered instrument board 16 can be checked again; meanwhile, usually can also depending on recognizing the information on the second clustered instrument board 18 in the visual field 56, wherein; in the visual field 60, chaufeur 48 can judge the activity of the perimeter in the visual field 56,58 instantaneously.Therefore, just at once things can be found while chaufeur 48 checks perimeter and the first clustered instrument board 16, as appeared at the pedestrian 62 of front (representing with arrow X1 in Fig. 2 and Fig. 3), therefore, chaufeur 48 can control vehicle 11 fast because of the appearance of pedestrian 62.

When its sight line 49 (is represented by arrow X1) from outlook 37 (see Fig. 2) by chaufeur 48 toward the front, the upper end of the panel 17 of the first clustered instrument board 16 is projected in the reflection archwise on instrument carrier panel 14 along bearing circle 12.Measure by the vertical direction in Fig. 1, the height of the panel 17 of the first clustered instrument board 16 is less than the height of the panel 38 of the second clustered instrument board 18.Therefore, chaufeur 48 obtains the absolute visual field of perimeter near the boundary line 45 of front windshield 44.

In sum, for the vehicular instrument device 10 in the present invention and the vehicle 11 being provided with vehicular instrument device 10, due to the display centre 19 of the first clustered instrument board 16 and the display centre 21 roughly coaxial setting each other of the second clustered instrument board 18, so the sight line of chaufeur 48 is only needing to move in vertical direction.The position residing near boundary line 45 due to the first clustered instrument board 16 is darker than the position residing for the second clustered instrument board 18, and the instruction on the first clustered instrument board 16 is by depending on recognizing in the outside of bearing circle 12, so, during the perimeter that its sight line 49 (is represented by arrow X1) through front windshield 44 by chaufeur 48 toward the front, also can watch the display surface (panel 17) of the first clustered instrument board 16 with comparalive ease attentively.So compared with the vehicular instrument device 51 in comparative example, the vehicular instrument device 10 in present embodiment and vehicle 11 can make the sight line 49 of chaufeur 48 move less distance.
